I love it. Simple and well designed. This is exactly the kind of thing you would hope emerges from a prompt like this. The art style is good. The levels feel like a lot of thought went into each of them. I felt like I could've kept playing for a long time and could see myself buying a game like this.
My only issues: a couple of times it felt like my clicks weren't registering and I had to click a few times to get it to flip. Also, I personally felt like the sound effects were a little grating. Could've just been the volume, but I think maybe a little polish could be directed there if you keep working on this.
Great stuff! I hope to see more of it in the future.
